The class is introductory but the additional readings are in depth. They also give you a tool to design your own land on Google Maps. Or you could do a design of the grand canyon if you wanted to.
I signed up for the course last year when they offered it. Seemed good and well setup though I did not complete the course. Got too busy with my homestead tasks and the course being free got pushed to the side.
But I did sign up for it again
Cultivate abundance for people, plants and wildlife - Growing with Nature
If you do nothing else download each lecture and as many of the additional readinga as you can and use the online design tool if you have time after that.
